What are the stages of marijuana growth?

If you are starting to grow cannabis, you must know all the changes that your plants experiment during their life cycle, so you can be more aware of the care they need during each stage of their growth.

If you are interested in knowing each of the phases; your plants go through. Look at this note, and discover each of them.

1- Germination phase

The first phase your cannabis plants go through is the germination stage, which begins with the seed.

Generally, a cannabis seed takes approximately 24 to 72 hours to germinate. Although in some cases, this task can take up to 10 or 12 days. There are different ways to germinate seeds. The easiest is the paper towel method.

When the seed opens and begins to show the first white root, it will start to develop, and finally, you will see the first two oval leaves, called cotyledons, grow. Now it is a seedling!

2- Seedling phase

As we mentioned, the seedling period begins (after germination) when the first pair of leaves, the cotyledons, emerge. And it usually lasts between two to three weeks.

During this period, a light cycle of 18/6 is usually recommended, 18 hours of light per day and a period of 6 hours of darkness.

In this phase, your plant will develop more of the typical cannabis leaves. At first, the leaves will only have a single leaflet the plant grows; it will get the mythical 5-7 leaflet leaves.

Once the leaves develop with the correct number of leaflets, you can take for granted that the seedling phase is over.

3- Vegetative phase

This phase takes approximately 3 to 16 weeks, depending on the genetics of each strain. During this phase, the ideal lighting cycle is 18/6. Your plant should already be moved to a larger pot because of this stage where most growth occurs.

As your cannabis grows, you will also need to increase the amount of water during watering. In the vegetative phase, your flowers will need other nutrients, a higher nitrogen level that contributes to the growth of stems and leaves.

This stage ends when you change the lighting cycle to 12/12, 12 hours of light, and 12 hours of darkness. In outdoor growing, this happens naturally when the days begin to shorten as the season’s change.

4- Flowering stage

The flowering phase has a time of 8 to 11 weeks, is the final stage of growth of a cannabis plant. It is in this phase when you will start to see those sweet and resinous buds. Here you should make sure that your fertilizers are especially rich in potassium and phosphorus.

To activate this stage, you will have to change the light cycle to 12/12, in the case of photoperiodic strains. Autoflowering strains, on the other hand, do not need variations in the light/dark phase to start flowering, as they do it automatically according to their age.

Once the buds have reached full maturity, it’s time to start your long-awaited harvest.
